da.Fill(ds, "Landlord")
dt = ds.Tables(0)
txtid.DataBindings.Add("Text", dt, "LandlordID")
txtplot.DataBindings.Add("Text", dt, "Plot No")
txtname.DataBindings.Add("Text", dt, "Name")
txtaddress.DataBindings.Add("Text", dt, "Address")

Maybe you have used a keyword, space, changed the file name.

Remove the Exception handling block and specify the Error that occurrs to enable me to evaluate the problem.

Hi,

The first error, it usually is generated when u have Re-Named the form in the Solution Explorer. Its a good idea to change the name of the form in Property Sheet.

Regrading second problem, check if u have a Primary/Unique Key for the ID column. If key is there and u r trying to save duplicate / null value, then u may not get any error but, data is not saved in database.

Remove the Try-Catch and check for any error.
